That is force is equal to the extension times the spring constant (f=k e). The number of oscillations per unit time is equal to the frequency. Frequency is measured in units referred to as hertz (Hz). The motion of a simple pendulum is one of the phenomena that can be used to approximate the simple harmonic motion. The motion is sinusoidal and is a demonstration of resonant frequency that is single (Dunwoody 10). A pendulum is a simple set up in which a string is attached to a small bob. The string is clamped, and when it is displaced, it swings in a to and fro motion. The time that would be taken to complete one oscillation is referred to as periodic time (T). The periodic time depends on the length of the pendulum and the acceleration due to gravity (g). That is
When a body is vibrating, its potential energy is converted to kinetic energy (Dunwoody 13). Studies advanced on a simple pendulum reports that the period value depends on its length. Another study argues out that the important property of a pendulum which makes be used in timekeeping (isochronism) (Dunwoody 15). This study identified the period as the pendulum’s prime property and that it depends on the square root of the pendulum’s length. This paper explores an experiment of simple harmonic motion by studying a pendulum. The hypothesis of this experiment is that increasing the length of the pendulum shall increase the periodic time (T) of a simple pendulum.
The simple pendulum was set up. The set up was made up of three regions. The centre was the pendulum. The length of the pendulum was chosen for the pendulum by using the slider on the left side of the screen. This value was recorded in the data table. The amplitude was raised to about 20 degrees. This value was equally recorded in the data table. The start animation button was clicked, and when the pendulum passed its lowest point, the timer was started. The time taken for
